SPRINKLER Russian patent published in 2017 - IPC A62C31/02 

FIELD: fire safety.

SUBSTANCE: in the sprinkler, containing a housing, an atomizing device and an element of automatic actuation for the predetermined room temperature excess, the body is formed as a cylindrical sleeve with windows on its side surface, and at one end of the cylindrical sleeve facing towards the atomizing device there is the partition, wherein the atomizing device is designed as a socket, formed by a part of the spherical surface with thickness "s" and in which there are made radial slits, at that the socket is attached to the end face surface of the sleeve by means of at least two arcs, located in the conical surface, the upper part of which is fixed at the partition, and the socket is fixed at the lower part, which is a part of the spherical surface, bounded by the inner and the outer hemispheres with thickness "s" within the range÷ 15mm. The hemispheres center lies on the line, connecting the cylindrical sleeve axis and the partition axis, and on the spherical surface from its outer side, there are at least three slots, the axes of which are located at the radial with respect to the hemisphere lines, and in the peripheral part of the hemispheres there are at least three throttle holes, the centers of which lie in the plane parallel to the diametral hemispherical plane, which is perpendicular to the cylindrical sleeve axis, and the axes of which intersects at the point, lying on the cylindrical sleeve axis, and form the acute angle with this axis in the plane of the drawing.

EFFECT: increase of the fire extinguishing effectiveness by the atomizing device introduction, which allows to obtain the fire extinguishing liquid fine flow or the foaming agent solution.
